  • Hex socket head cap screws made of PEEK containing glass fiber for increased strength. The tensile strength of the material is approximately 1.7 times that of ordinary PEEK.
  • PEEK is a thermoplastic super engineering plastic superior in physical and chemical properties.
  • Excellent chemical resistance. It remains almost unaffected by chemicals other than concentrated sulfuric acid, concentrated nitric acid, and concentrated hydrofluoric acid.
  • With excellent heat resistance and water resistance, it retains strength at high temperatures.
  • It features outstanding resistance to wear, shock, and fatigue.
  • It also has high flame retardance which clears the UL 94 V-0 standard.
  • The properties and precautions of plastic screws ⇒Plastic Screws
  • Knurling on the head of SPEG-C has been eliminated in order to distinguish it from PEEK hex socket head cap screw SPE-C that contains no glass fiber.

Precautions for Use

Because a cumulative pitch difference is created when PEEK screws are manufactured, use a 20 mm or less fit with female thread.
